Problems solved by technology

However, due to disease or injury, the heart rhythm may become irregular resulting in diminished blood circulation.
If the pace pulse energy is too low, the pace pulses may not reliably produce a contractile response in the heart resulting in ineffective pacing.
If the pace pulse energy is too high, the result may be patient discomfort as well as shorter battery life.

Embodiment Construction

[0024]In the following description of the illustrated embodiments, references are made to the accompanying drawings that form a part hereof, and in which are shown, by way of illustration, various embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized, and structural and functional changes may be made without departing from the scope of the present invention.

[0025]A variety of cardiac rhythm management devices may be used to detect and treat various arrhythmias of the heart. Such devices include, for example, pacemakers for treating heart rhythms that are too slow (bradycardia), and cardioverter / defibrillators for detecting and treating fast cardiac arrhythmias, such as ventricular tachycardia (VT) and / or ventricular fibrillation (VF). Pacemakers regulate the heart's rhythm by delivering low energy electrical stimulation to the heart to produce contraction of the heart tissue. Cardioverter / defibrillators treat cardiac tachy...

Abstract

A template selection method involves providing a plurality of templates representing a type of cardiac event. One or more characteristics of each template are evaluated. The evaluations are compared and a template is selected as a current template based on the comparison.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to implantable medical devices and, more particularly, to selection of templates characterizing various types of cardiac events.BACKGROUND OF THE INVENTION[0002]Rhythmic contractions of a healthy heart are normally controlled by the sinoatrial (SA) node, specialized cells located in the upper right atrium. The SA node is the normal pacemaker of the heart, and when functioning normally, the heart produces rhythmic contractions and is capable of pumping blood throughout the body. However, due to disease or injury, the heart rhythm may become irregular resulting in diminished blood circulation. Arrhythmia is a general term used to describe heart rhythm irregularities arising from a variety of physical conditions and disease processes. Cardiac rhythm management systems, such as implantable pacemakers and implantable cardioverter / defibrillators (ICDs), have been used as an effective treatment for patients with serious ar...
